A 14-person medical team rushed into real-life action at a Staten Island hospital yesterday in response to a make-believe explosion at a chemical plant.

Volunteers smeared with fake blood and dirt and screaming, “My eyes are burning!” and “Help me!” played injured workers who had come by ambulance or walked into St. Vincent’s Hospital in RandallManor.

Medical personnel in hazmat suits took the phony patients through decontamination showers set up outside the emergency room, washed them down, then led them back into the ER for further treatment.

Security personnel, meanwhile, worked to keep order as some of the “injured” flocked in panic toward the emergency room.

“We started disaster training shortly after 9/11,” said hospital spokesman Jim McMahon. “Staff members have been trained in nuclear, chemical and biological preparedness.” He added that the purpose of the drills, which pulled workers from all sections of the hospital, was, among other things, to “keep the staff tuned.”
